- ASTEROIDS II MACHINE-READABLE DATA BASE - MARCH 1988 VERSION
-
- This data set was assembled by E. F. Tedesco, Jet Propulsion
- Laboratory, in March 1988 from files provided by the contributors noted
- below. These files constitute the machine-readable version of Part VI -
- Tabulation, of the book "Asteroids II" 1988 eds. R.P. Binzel, T. Gehrels,
- and M.S. Matthews (Tucson, Arizona: University of Arizona Press). Each
- chapter in Part VI will contain a brief introduction followed by the
- tabular material. In many cases the chapters will be a subset of the
- machine-readable form of the data set. For example, one of the enclosed
- files is a tabulation of proper elements computed by J.G. Williams; these
- will not appear in the book.
-
- The possibility exists that some of the enclosed files, for example
- the discovery circumstances file, will be updated prior to publication,
- hence, the version which appears in the book may differ from that
- contained herein. For this reason references to data obtained from
- these files should reference them explicitly. For example a reference
- to the rotation data base should read "Lagerkvist et al., 1987" in the
- text and (for the floppy disk version) "Lagerkvist, C.-I., Harris, A.W.,
- and Zappala, V. (1987). Asteroids II machine-readable data base: March
- 1988 floppy disk version." in the references section.
-
- The files contained herein have been deposited with the National
- Space Science Data Center, Code 633.4, Goddard Space Flight Center,
- Greenbelt MD 20771 under the data set name: "Asteroids II machine-readable
- data base: March 1988 version". The time between submission of a data set
- to the NSSDC and the time it becomes available to a requester is on the
- order of three to six months. Their average processing time for a request
- is three to four weeks. This data set will be available from NSSDC only
- on 9-track magnetic tape. If you have used the NSSDC version of this data
- set then the full reference should read, for example, "Lagerkvist, C.-I.,
- Harris, A.W., and Zappala, V. (1987). Asteroids II machine-readable data
- base: March 1988 version, National Space Science Data Center, Greenbelt
- MD". Naturally, a datum on an individual asteroid, at least one you are
- discussing in detail, should reference the original source.
-
- The Asteroids II machine-readable data base: March 1988 version
- consists of the following files received by me on, or prior to, 29 March.
